I have a ThermalTake 750w PSU and I have just ordered a 3870 X2 - Ive done a stupid thing (again) and baught the card before doin some research...will my psu run the gfx card fine...along side 2gb DDR3 ram and a Q6600 not overclocked?

Thanks in advance, quick replys greatly appreciated!

definately. I'm fairly confident that that card would run fine on even a quality 500-watt. Companies trick you into thinking you need way more power then you really do. I have a very good quality Corsair VX550-watt power supply, that will probably be fine with even 2 8800 GTS cards.

Definitely! I run mine fine on 600W ocz.

I'm running on a Silverstone 750, with a dual core and everything is fine. It would have been nice to have the 8-pin PCIe connector on the P.S. though. I spent $15 to get an adaptor shipped.

According to the documentation, the card needs only a 550 watt PSU. I'm using an Antec Neo 650 and it runs fine. You'll need a six pin and an 8 pin power connector if you want to overclock.

Xbit Labs said their 3870x2 worked with two 6 pin PCIe connectors, my card's factory overclocked and I had to get a PSU with a 6+2 (8) pin connector. I couldn't get it to work with two 6 pins on an Antec Neo 550, so I upgraded the PSU.

Now, all I have to do is upgrade the CPU LOL.

Nice one! Thank you all for your replys!

One last question...how are the 3870 X2s? I've always got ATi and when i saw the card it looked the s**t! lol! Had to get it and the benchmarks and reviews I read confirmed that it was a great card. So with hands on experience, what do you guys think?

With the correct drivers the card is great. The stock cooling is not very good for over clocking the card though, and the ATI drivers don't do a good job keeping the fan speed where it should be.
